ac9c9d8efc msdk: use cached response for DMABuf when the frame size is same
User is seeing corrupted display when running `videotestsrc !
video/x-raw,format=NV12,width=xxx,height=xxx ! msdkh265enc ! msdkh265dec
! glimagesink` with changed frame size, e.g. from 1920x1080 to 1920x240

The root cause is a same dmabuf fd is used for frames with
different size, which causes some unexpected result. This patch requires
cached response is used for frames with same size only for DMABuf, so a
dmabuf fd can't be used for frames with different size any more.

1bcf44bb1f msdk: Fix increasing memory usage in dynamic pipelines
Our context is non-persistent, and we propagate it throughout the
pipeline. This means that if we try to reuse any gstmsdk element by
removing it from the pipeline and then re-adding it, we'll clone the
mfxSession and create a new gstmsdk context as a child of the old one
inside `gst_msdk_context_new_with_parent()`.

Normally this only allocates a few KB inside the driver, but on
Windows it seems to allocate tens of MBs which leads to linearly
increasing memory usage for each PLAYING->NULL->PLAYING state cycle
for the process. The contexts will only be freed when the pipeline
itself goes to `NULL`, which would defeat the purpose of dynamic
pipelines.

Essentially, we need to optimize the case in which the element is
removed from the pipeline and re-added and the same context is re-set
on it. To detect that case, we set the context on `old_context`, and
compare it to the new one when preparing the context. If they're the
same, we don't need to do anything.

ef37446460 msdkdec: align frame list using decoded timestamp
Before this change decoder used the oldest frame in the list to pair it
with the decoded surface. This only works when there's a perfect stream
like HEADERS,SYNCPOINT,DELTA...

When playing RTSP streams we can get imperfect streams like HEADERS,
DELTA,SYNCPOINT,DELTA... In this case decoder drops the frames
between HEADERS and SYNCPOINT which leads into using wrong PTS on
the output frames.

With this change we inject the input PTS into the bitstream and use it
to align the internal frame list with the actually decoded position.

Fixes playback with:
```
gst-launch-1.0 rtspsrc location=... latency=0 drop-on-latency=1 ! ...
```

bdf9a76226 Revert "msdkdec: make sure to use video memory on Linux"
Commit a1584b6 caused big performance drop if the downstream element
is not a msdk element because it is very slow to read data from video

da22ff3846 msdkvp9enc: fix width and height
The frame width and height is rounded up to 128 and 32 since commit
8daac1c, so the width, height for initialization should be rounded up to
128 and 32 too because the MSDK VP9 encoder will do some check on width
and height.

Sample pipeline:

video/x-raw,width=320,height=240,format=NV12 ! msdkvp9enc ! fakesink

f578eab6fd msdkenc: renegotiate when video info changes
Renegotiation was implemented for bitrate change. We can re-use
the same sequence when video info changes except that this can be
executed right away when receiving the new input format. I.e. no
need to wait for the next call to handle_frame.

a1584b6f99 msdkdec: make sure to use video memory on Linux
The block that sets use_video_memory flag is after the
the condition `if gst_msdk_context_prepare` but it
always returns false when there is no other msdk elements.
So the decoder ends up with use_video_memory as FALSE.
Note that msdkvpp always set use_video_memory as TRUE.

When use_video_memory is FALSE then the msdkdec allocates
the output frames with posix_memalign (see gstmsdksystemmemory.c).
The result is then copied back to the GstVideoPool's buffers
(or to the downstream pool's buffers if any).
When use_video_memory is TRUE then the msdkdec uses vaCreateSurfaces
to create vaapi surfaces for the hw decoder to decode into
(see gstmsdkvideomemory.c). The result is then copied to either
the internal GstVideoPool and to the downstream pool if any.
(vaDeriveImage/vaMapBuffer is used in order to read the surfaces)

a819f05851 msdkdec: free unlocked msdk surface before output buffer allocation
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/merge_requests/924
is trying to use video memory for decoding on Linux, which reveals a
hidden bug in msdkdec.

For video memory, it is possible that a locked mfx surface is not used
indeed and it will be un-locked later in MSDK, so we have to check the
associated MSDK surface to find out and free un-used surfaces, otherwise
it is easy to exhaust all pre-allocated mfx surfaces and get errors below:

0:00:00.777324879 27290 0x564b65a510a0 ERROR                default

b18be3562c msdk: ignore MFX_ERR_UNDEFINED_BEHAVIOR when loading a plugin
An issue can be seen when using msdkh265enc with bitrate change in
playing state. The root cause is the corresponding plugin is loaded
again.

Returning MFX_ERR_UNDEFINED_BEHAVIOR from MSDK just means the plugin has
been loaded, so we may ignore this error when doing configuation again
in the sub class, otherwise the pipeline will be interrupted

3bae199863 msdkdec: fix assertion 'frame->ref_count > 0' failed
Can happen if the oldest frame is the current frame
and if gst_video_decoder_finish_frame failed in which
case the current is unref and then drop instead of
just drop.
This patch also removes some assumptions, it was strange
to call unref and finish_frame in gst_msdkdec_finish_task.
In principle when owning a frame, the code should either
unref, or drop or finish.

2af672d00a msdkdec: log an error if leaking surfaces in finalize
The for loop in gst_msdkdec_handle_frame is error prone
about how it manages surfaces. Because sometimes it sets
the surface variable to NULL and sometimes it needs to free
it right away. So better to print an error if surfaces are
leaked to help with any change around the loop.

348494fd34 msdk: query hardware when checking MFX availability
msdk plugin is not used for sofware encode/decode as there are better
solutions available. Also, with MFX_IMPL_AUTO_ANY, if software decode
is not supported, the plugin will still load, but will then fail when trying to
run the (autoplugged) pipeline. With MFX_IMPL_HARDWARE_ANY,
the plugin fails and a better software decoder is auto-plugged.

a7dc407041 msdkdec: fix surface leak in msdkdec_handle_frame
Can be reproduced with:
  videotestsrc ! x264enc key-int-max=$N ! \

It happens with any gop size but the smaller is the distance N
between key frames, the quicker it is leaking.

fbeaa37b79 msdkenc: add need_conversion method
In future, a sub class of GstMsdkEncClass may decide a native format by
using this method, e.g. JPEG encoder may accept YUY2 input, however the
current implemation needs a conversion from YUY2 to NV12 before encoding.

In addtion, a sub class may choose a format for encoding if the input
format is not supported by MSDK, e.g. the current implemation does
UYVY->NV12 if the input format is UYVY. We may do UYVY->YUY2 for JPEG
encoder in future

cd883427e9 msdkdec: add parse callback for non-packetized input
commit 55c0d720 added the capability to handle non-packetized bitstream,
and there is a loop to handle multiple frames in a non-packetized buffer
in gst_msdkdec_handle_frame. However it is possible that a
non-packetized buffer still contains valid data but there is no long any
pending unfinished frame. Currently gst_video_decoder_decode_frame is
invoked to send a new frame with new input data, the situaltion is
repeated till an EOS is received. An application has to exit when
receiving an EOS, however there is still valid data in a
non-packetezied input buffer, hence some frames are dropped.

This fix adds a parse callback for non-packeteized input, a new frame
will be sent to the subclass as soon as the input buffer has valid data
